Film online - Dreamgirls (2006)

Detroit, the early 1960s. Curtis Taylor, Jr., a car salesman, breaks
into the music business with big dreams. He signs a trio of young women,
the Dreamettes, gets them a job backing an R&B performer, James
"Thunder” Early, establishes his own record label and starts wheeling
and dealing. When Early flames out, Curtis makes the Dreamettes into
headliners as the Dreams, but not before demoting their hefty big-voiced
lead singer, Effie White, and putting the softer-voiced looker, Deena
Jones, in front. Soon after, he fires Effie, sends her into a life of
proud poverty, and takes Deena and the Dreams to the top. How long can
Curtis stay there, and will Effie ever get her due?
